| Outline of Final Research Achievements |
The purpose of this research is to develop a watching system to prevent the leakage of privacy information from posted contents when using SNS. The goal is to implement a system that automatically analyzes user profiles based on information on SNS and supports healthy SNS usage. Specifically, in this study, we developed: algorithms for estimating by machine learning whether the contents posted are attracting attention or not; algorithm for estimating emotional classification of posted contents; algorithm for estimating user's occupation from posted contents. In addition, for practical use, we have used cloud environments for larger scale and experimentally implemented on real systems.
